4.2 TRAFFIC AND CIRCULATION <br /> volumes can vary. The volume differences result from daily fluctuations in traffic volumes. Intersections <br /> with stop control for only the minor street approaches were analyzed using the Highway Capacity <br /> Manual: Special Report 209 method. The intersections with all approaches stop controlled were analyzed <br /> using the All Way Stop Control(AWSC-ALL) method. All of the studied intersections are unsignalized. <br /> (Intersection level of service calculation worksheets are on file at the San Joaquin County Community <br /> Development Department.) <br /> TABLE 4.2-1 <br /> EXISTING INTERSECTION OPERATING CONDITIONS <br /> AM Peak PM Peak <br /> Intersection Control Device LOS Delay LOS Delay <br /> 1.

Davis/State Route 12 2-way stop E* NA E* NA <br /> NOTES: <br /> Delays are listed in seconds. <br /> NA = Not Applicable; minor street stop-controlled intersections do not yield delay. <br /> * = Listed LOS refers to minor street left-turn movement; overall intersection operates at LOS C or <br /> better. <br /> Source: Omni-Means, Ltd. <br /> As shown in Table 4.2-1,five of the six study intersections currently function at LOS A during both the <br /> AM and PM peak hours, indicating optimum operating conditions with little or no delays. At the <br /> intersections of Lower Sacramento/Forest Lake,Peltier/Ray,and Peltier/Davis the minor street approach <br /> volumes are very low. Combined with the moderate major street approach volumes,there are sufficient <br /> gaps in through traffic to allow vehicles to enter from the minor street, and vehicle queue lengths remain <br /> short. <br /> 4.2-4 <br />
